A return roller assembly that is designed for use as part of a conveyor assembly to improve the ability to clean the conveyor assembly. The return roller assembly includes a roller shaft that extends between side walls of a conveyor frame. A plurality of support rollers are positioned along the length of the roller shaft to support a lower run of a continuous conveyor belt. A spacer is positioned between each of the support rollers to define the position of the rollers along the roller shaft. The spacer can be snapped onto the roller shaft and includes a series of standoffs that space the inner surface of the spacer from the roller shaft. A series of cleaning fins extend radially from the outer surface of the spacer and impart rotation to the spacer relative to the roller shaft during cleaning with a spray of water. The spacer can be formed from an extrusion cut to length.

The present disclosure relates to a conveyor frame assembly that includes a pair of spaced side rails joined by one or more cross supports. Each of the side rails includes a dedicated wire channel and self-contained air flow cavity that enhances the functionality of the conveyor frame assembly. The air flow cavity and the wire channel are formed as part of the side rails separate from typical attachment slots that receive T-shaped connectors. The cross supports utilized with the conveyor frame assembly are attached to the side rails by upper and lower connectors that are each accessible from the top of the conveyor frame assembly. Specifically, the cross support includes a center web and laterally offset attachment webs that allow for easy and convenient construction and field modification of the conveyor frame assembly.

A conveyor assembly has a continuous conveyor belt driven between a pair of spaced side frame members by a center drive assembly having a pair of spaced side plates connected to the side frame members. A drive roller arrangement is driven by a drive motor arrangement coupled to the drive roller arrangement to move the conveyor belt. A freely rotatable guide roller arrangement is slidably mounted between the side frame members and the side plates between an operating position in which the conveyor belt passes around the guide roller assembly before engaging the drive roller arrangement, and a cleaning position in which the guide roller arrangement is slidably removable away from the side frame members and the side plates and out of engagement with the conveyor belt. The guard structure is retained in the operating position by elongated retaining pins that are pushed into a frictional engagement with the side plates, the guide roller arrangement and the guard structure, and removed to the cleaning position by pulling the retaining pins out of the frictional engagement. Each of the guard structures includes a roller adjustment device that can be selectively operated to adjust the orientation of the guide roller assembly between the spaced side frame members of the conveyor assembly.

A locking assembly for use with drive sprockets positioned to drive a conveyor belt supported by a conveyor frame assembly. The locking device includes a main body that extends through each of the drive sprockets positioned along a drive shaft of the conveyor assembly. The locking device includes spaced receiving notches that each receive one of the drive sprockets to maintain a desired spacing between the drive sprockets when the locking device is in its locking position. The locking device is movable to a release position to independently release each of the drive sprockets from the locking device. Once released, each of the drive sprockets are movable along the length of the drive shaft to facilitate cleaning of the conveyor assembly. When the locking device is in its locking position, the combination of the locking device and drive sprockets is movable along the longitudinal length of the drive shaft.
